Abstract

Se revela un codificador para codificar una señal de audio, que comprende un analizador configurado para analizar la señal de audio y para determinar coeficientes de predicción de análisis de la señal de audio. El codificador comprende además un convertidor configurado para derivar coeficientes de predicción convertidos de los coeficientes de predicción de análisis, una memoria configurada para almacenar una multitud de valores de corrección y una calculadora. La calculadora comprende un procesador configurado para procesar los coeficientes de predicción convertidos para obtener factores de ponderación espectrales. La calculadora comprende además un combinador configurado para combinar los factores de ponderación espectrales y la multitud de valores de corrección para obtener factores de ponderación corregidos. Un cuantificador de la calculadora está configurado para cuantificar los coeficientes de predicción convertidos utilizando los factores de ponderación corregidos para obtener una representación cuantificada de los coeficientes de predicción convertidos. El codificador comprende un formador de flujo de bits configurado para formar una señal de salida en base a la representación cuantificada de los coeficientes de predicción convertidos y en base a la señal de audio.
